bogus
adjective | BOH-gus

Definition

: not genuine : counterfeit, sham

You may know bogus as a slang word meaning "uncool" or simply "no good," but did you know that bogus has actually been a part of English since the early 1800s? Not only was the word coined then, it was actually doing some coining of its own, so to speak. Back then, a bogus was a machine used to make counterfeit coins. No one knows for sure how this coin-copying contraption got its name, but before long bogus had also become a popular noun for funny money itself or for a fraudulent imitation of any kind. The more general "phony" adjective began being used about the same time.
